This is a conceptual Tokyoflash watch with a built-in breathalyzer for determining your sobriety.The watch has been created to allow the wearer to keep track of their blood alcohol content.


This concept is an LCD watch design which can be read at a glance because it has an ‘always on’ digital LCD display. It also features a multi-colored LED backlight, perfect for night time viewing. You simply have to touch the light function to illuminate the display.

After drinking, touch the button to activate the Alcohol Test Function, blow into the port and await the result. Your blood alcohol content reading gives an indication of your level of sobriety.


Once the content within your blood goes to a certain level the screen colour changes from green to red. Watch the two videos after the jump to see the new TokyoFlash Breathalyzer Watch Concept in action.
